Hello, i have a few question about socket in c++!
First question, let's say that he writes a server for the game in which he will play 200 people at once, but accept is blocked because he already serves one client, how to deal with it?
Second question, how to download a list of all currently connected clients, so that you can then send a package to everyone?

You can use non-blocking sockets to have the accept() call not blocking, or use select() to find out which socket has data available, the listen socket indicates data available on select when there is a new connection.

For the 2nd part, you need to keep track of all the connected sockets yourself.
